This is the second router I have seen that messes up reverse lookup of
ip-adresses. I will put this on my to-do list to work around this. A
solution will take some time and will not be in 1.2.22 as the merge
window for new features has already closed. I will see if I can do the
change in both the sane backend and in cups-bjnp. I have seen a fritzbox
return "noname" when a reverse lookup is done, but this one is
definitely even more incorrect. Localhost is normally 127.0.0.1....
your work-around is the correct solution for now.
I leave your other issue for Nicolas to answer, as he is the maintainer
of the backend
kind regards, Louis
